A CORPORATION OF NEW" DROP-WIRE SUPPORT Application filed March 2, 1928.Serial No. 258,646.

Our invention relates to the telephone and telegraph art and moreparticularly to a drop wire support.

Our invention further relates'to articles of manufacture, combinationsand sub-combinations and details of construction all of which will bemore fully hereinafter described and pointedout in the claims.

In the drawings we have shown different embodiments of our invention,but it is of course to be understood that our invention is not to beconfined to these particular embodiments shown by way of illustration. 7

In this art it is very important that the insulation of the drop wireshould not be marred, broken or ruptured, which would damage the dropwire and lead to short-circuiting. We have, therefore, formed our dropwire support so that the insulation of the drop wire will not be injuredwhile it is supported and clamped in our drop wire support.

' member to the tongue.

We further insure that rain, snow and sleet will not be caught and heldin our drop wire support, but on the contrary, the drop wire in oursupport will be protected from the elements.

In Figs. 1 to 6 inclusive, our drop wire support is formed of a box 1having sides 2 and 3, the sides 2 and 3 being provided with two or moreinclined slots 44. The sides are also preferably provided with bent por-Both the box 1 and the tongue 7 are prefer- I ably made from stampedsheet metal, the inclined slots H being cut out, a portion of the blankbeing bent to form the sides 2 and 3 of the box, and a portion of thesides being further bent to form the bent portions 55, either at thesame or a subsequent operation. We also preferably provide the interiorof the box 1 with a roughened surface 8to en gage with the drop wire 9as shown more clearly in Figs. 1, 2 and 6. r

In the form of our invention illustrated in Figs. 1 and 8, the tongue isprovided with a single hole or aperture 10 to cooperate with a separatefietxible tie member 11 which may be a wire formed of copper orother'suitable material, one end 12 being threaded through the hole 10in the tongue and thence wrapped around the tie member so as to securethe tie Theother-end 13 of the tie member 11 is passedover the support,preferably an insulatingknob 14 secured by a screw or other member 15 ina wall or other suit-able support 16. The free end of tie member 11 ispassed around the groove 17 in the insulating knob 14 and then its end13 is wrapped, one or more times, around. the tie member as shown inFig. 13 which will secure the tie member with its tongue 7 to theinsulating knob 14.

In use thebo-x 1 is placed over the drop wire 9 and then the lugs 66upon the tongue 7 are passed through the respective bowed portions' 5-5in the sides 2 and 3 of the box so that these lugs may ride in theinclined slots et-4 in the box. The free end of the tie member 11 isthen passed around the insulating knob 14. in the manner previouslydescribed. The drop wire 9 is then, preferably, passed over theinsulating knob 14 and led to its desired terminal. In some cases where,for example, the end 33 of the drop wire is short, it may be threadedthrough the box 1 while the tongue 7 is located within the box andbefore any clamping action is exerted by the lugs 6., 6 and inclinedslots 4, l.

It will be clear that with the tongue 7 secured to the iixed insulatingknob 1% that pressure or strain upon the drop wire 9 will cause the box1 to move with the drop wire and cause the inclined surfaces 4 i, in thesides 2 and 3, to ride under the lugs 6-6 on the tongue and, in thismanner, increase the grip of the drop wire support upon the drop wirewithout, however, marring in any particular the insulation of the dropwire 9.

To remove the drop wire support it is simply necessary to cause arelative movement between the box 1 and the tongue 7 to release the lugs66 from their inclined surfaces H and bring the lugs adjacent to thebowed portions 5, when the tongue can be withdrawn and the box 1 removedfrom the drop wire 9. This will permit the drop wire to be again used inany other location desired, for its insulation will not be marred. Bysimply bending back the end 13 of the tie member this member can bereleased from the insulating knob ll so that our drop wire support canalso be used again in any other loca tion.

Instead of having a. tongue 7 provided with a single hole for a flexibletie member,

we may provide it with two holes 1919 (F 7) and thread the end 12 of thetie member 11 through both holes, and then wrap it around the tie memberas shown in 7. Or we may employ a. tie member 20 bent back upon itselfto form a loop to fit over the insulating knob 14, the two ends 21-21being bent to form hooks to hook into the holes 1919 in the tongue 7. Wehave shown another modification in Fig. 9 in which a tie member 22 isbent to form a loop to fit over a support, such as the insulating knob14, its two ends 2323 being threaded through the holes 1919 and thenseparately wrapped around each arm of the loop.

In some locations it is not necessary to use any flexible tie member. Vie have shown a modification of our invention in Fig. 12 in which thetongue 24: has one end 25 bent up at substantially right angles to theremaining portion and provided with a hole 26 for the reception of anail, screw or other member such as 31 in Fig. 10.

We have shown in Figs. 10 and 11a double drop wire support 27 having adouble tongue 28, (Fig. 11) with different sets of lugs 6, 6 at eitherend, its intermediate portion being bent at substantially right anglesto form a supporting member 29 provided with a hole 30 for the receptionof a screw or other securing member 31 (Fig. 10). With the double tongue28 we employ two boxes 11 each cooperating with a different set of lugs(i6 on tongue 28 so that the drop wire 9 is clamped by both boxes 1-1 incooperation with the respective sets of lugs 66, one set coopera 'ngwith each box as shown in Fig. 10.

Having thus described this invention in connection with illustrativeembodiments thereof, to the details of which we do not desire to belimited, what is claimed as new and what is desired to secure by LettersPatent is set forth in the appended claims.

What we claim is 1. In a drop wire support the combination of a slidablebox provided with two sides each side being provided with inclinedperforations extending entirely through the sides forming inclinedslots, and with convex or bowed portions, and a tongue provided withmeans to pass through the convex or bowed portions to cooperate with theinclined perforated slots in the sides of the box.

2. In a drop Wire support the combination of a slidable box providedwith two sides each side being provided with inclined perforationsextending entirely through the sides forming inclined slots, a portionof the sides adjacent the slots being bowed or convex to formstrengthening entrance passages for lugs on a tongue, and a tongueprovided with lugs adapted to pass through the bowed or convex portionsand cooperate with the inclined perforated slots in the sides of thebox.
